Patent DE-2610385-A1 (DE)
Title: Ferrite sintering pusher furnace - with nitrogen flows in preheating and cooling zones at specified directions (NL 14.9.77)
Inventor: PETZI FRITZ
IPC: F27B9/04
Filed: 1976-03-12
Abstract: A pusher-type tunnel furnace with a controlled atmosphere for sintering ferrites consists of a preheating zone, a high temp. zone and a cooling zone. In the preheating zone an atmospheric flow is maintained within the furnace space, directed from the inlet towards the high temp. zone and most of it is discharged at the transition between the two zones. A similar flow is maintained in the reverse direction in the cooling zone and discharged at the transition. This eliminates the undesirable condensation of bonding medium vapours in the preheating zone. Any excessive temperature rise of the sintered articles by exothermic reactions is suppressed.

Title: Fault location in ferromagnetic rods - uses alternating field for additional axial magnetisation without later demagnetisation
Inventor: KRAMER GERHARD
IPC: G01N27/90
Filed: 1976-05-20
Abstract: A method and device is used for fault location in elongated ferromagnetic test material (2). It uses a magnetic flux to detect faults on or beneath the material surface causing flux variations outside the surface which are detected and converted into electrical fault signal voltages. The device obviates the later demagnetisation of the test without using the advantage of additional magnetisation in the axial direction. The additional magnetisation is produced by an alternating magnetic field whose frequency is lower than that of the primary field and whose amplitude reaches a sufficient level for additional magnetisation during part of the field cycle. Parts of the signal voltage winding with field null transitions are suppressed.

Title: Sail board for wind-surfing - has wear-resistant universal mast-foot joint including elastic core of e.g. EPDM rubber
Inventor: KUMMETZ HANS-ERICH
IPC: B63B35/79
Filed: 1977-08-02
Abstract: Sail board has a sail attached to a mast, and a mast-foot joint holding the mast securely whilst allowing it to rotate and tilt freely. The mast can be easily detached from the foot joint. A joint section in the form of a bush is fixed to the board and is attached to a complementary, bush-like detail on the mast, by means of a block or peg of material with a high degree of elasticity and resistance to water and/or radiation, projecting from the inside of the fixed bush. The mast-foot joint may be attached to the sail board by means of an anchoring cable passing through the cylindrical block forming the core of the joint, and this block is pref. of an elastomer such as EPDM rubber. This has uniformly similar resistances to compression and tension in all radical directions. The surfaces between the sockets and the rubber block may be given a coating of an adhesive such as one comprising a mixt. of an elastomer and a synthetic resin. The arrangement overcomes the failings of known mast-foot joints by providing a universal joint proof against breakage by the action of wind and water, and against wear generally. The sailor's feet cannot be harmed by the movement of the mast.

Title: Control of stepper motor winding current overlap time - is designed to obtain very high utilisation of active material
Inventor: HEINE GUENTER ING GRAD
IPC: H02P8/16
Filed: 1977-09-17
Abstract: The system is used for the control of a stepper motor (1). At low step frequencies the overlap time between the current flow in one phase and the next is controlled to a very small value approaching zero. Typically the time is one millisecond. With a short overlap time the power loss in the windings is greatly reduced when compared with a constant ratio overlap. The loss reduction permits the use of a higher current at low speeds, and at low speeds, and hence a higher torque for the same heating affect. Alternatively the amount of active material can be reduced for a given torque.
